Tail gate box, table, and sink

ABSTRACT

A fold-up combination tail gate table, sink, and storage box for the rear of a pickup truck containing a box or table made of steel, molded epoxy resin plastic or other suitable material mounted pivotally on an arm that can be attached to and removed from the truck&#39;s tail gate. The assembly is pivoted from a folded position on the closed tailgate to an open position from the open tailgate. It remains locked by forces on the swivel arm contacting the table under the box as well as forces between the arm and the tailgate attach. In the unfolded position, the assembly is extremely stable and can support considerable weight. It becomes a table, a storage container, a sink for liquids, and with several optional circular holes, a holder for bottles, drinks or other containers. When the lid is closed, the lid itself becomes available for further use as a table. The assembly can be used for display, food preparation, fish cleaning, tool or food storage, or as a workbench as well as numerous other uses.

This is a Continuation-In-Part of application Ser. No. 08/533,066 filed on Sep. 25, 1995, now U.S. Pat. No. 5,575,521.

BACKGROUND

1. Field of the Invention

This invention relates generally to the field of portable utility platforms for vehicles and more particularly to an extendable truck tail gate box that can contain a sink for water and can act as a table and workbench as well as a storage compartment.

2. Description of the Related Art

Previous systems include simple fold away tables for "tail gate parties", and other types of platforms that extend from the trunk of a car, or the side or back of a truck, to allow eating, food preparation, and other activities. There are also several types of tool storage boxes and work benches that attach to the front or rear of a car or truck that are used by the various trades. In addition, there are fold out tents, beds and camping affairs.

Pickup trucks are many times used as recreational vehicles for camping, pulling boats, etc. What is badly needed is a combination table, workbench, storage box, and sink (for washing dishes, etc.) that will fold out or extend from the rear of a pickup truck, when the tail gate is down, to allow various types of utility use for work, camping, fishing, hunting, and numerous other outdoor activities. This tail gate box could be used to store camping supplies, fishing supplies, tools, food, or anything else. It would have compartments that could be used as sinks with drain holes for washing dishes, cleaning fish, or any other use for a liquid basin. The combination sink/storage compartments would be removable when a simple table was required. This tailgate box would be easily adjustable to different heights without cumbersome locks.

SUMMARY OF THE INVENTION

The present invention relates to a fold-up combination tail gate table, sink, and storage box for the rear of a pickup truck. The entire assembly contains a box or table made of steel, molded epoxy resin plastic or other suitable material mounted pivotally on an arm that can be attached to and removed from the truck's tail gate.

The assembly folds compactly onto the interior of the tailgate when not in use. This allows the tail gate to be raised and secured for driving. When the tail gate is down, the assembly can be pivoted outward behind the truck. One or two folded legs can be moved into position and then extended to contact the ground or road surface behind the truck. An alternate embodiment has no legs and is held firm by bracket. The box can be accessed from the rear with its lid opening toward the truck or away from it. The entire box is optional, and the present invention can be used as simply a utility table.

After the assembly is pivoted into position, it remains locked by forces on the leg(s) and the swivel arm contacting the table under the box as well as forces between the arm and the tailgate attach or by forces in the locking brackets in the legless embodiment. In the unfolded position, the assembly is extremely stable and can support considerable weight. In the unfolded position the present invention thus becomes a table, a storage container, a sink for liquids, and with several optional circular holes, a holder for bottles, drinks or other containers. When the lid is closed, the lid itself becomes available for further use as a table. The present invention can be used for display, food preparation, fish cleaning, tool or food storage, or as a workbench as well as numerous other uses.

The present invention can be removably attached to the truck's tail gate with a strap, multiple straps, or a simple strap turnbuckle arrangement, or the assembly can be permanently installed. The entire assembly can be totally removed for storage when the truck must be used for other purposes. Since re-attachment is fast and simple, it only takes moments to put it on the truck before a field trip or camping trip.

DESCRIPTION OF PREFERRED EMBODIMENTS

An embodiment of the present invention is shown in FIG. 1. Here the tailgate 2 of a pickup truck 1 can clearly be seen. The tailgate table 6 is shown in the unfolded position. It is supported by a set of telescoping legs 7 and a pivot arm 4 attaching it to the tailgate 2 via a tailgate attaching device that will be called a tailgate attach. The tailgate attach can be a strap, set of straps, or a permanently mounted bracket. When a strap is used as a tailgate attach, a turnbuckle or set of turnbuckles can be used to tighten it.

FIG. 2 shows a side view of the setup of FIG. 1. Again the table 6 is shown supported on a set of legs 7. While the figures show an embodiment of the invention with telescoping legs, it is not necessary to the functioning or structure of the invention that the legs telescope. In fact, any means of support for the rear of the table will work with the present invention. The legs 6 fold laterally when the table is put back in the truck for storage.

The pivot arm 4 can again be seen in FIG. 2 extending between the tailgate 2 and the base of the table 6. An upper pivot support 5 and a lower pivot support 3 can also be seen. These pivot supports can be constructed from vertical metal plates or box stock, molded plastic, or other strong suitable material. These supports 3 and 5 contain a pin that the pivot arm 4 freely rotates on. While metal is the preferred material for the pivot and pivot supports; they can be made of any strong and durable material.

One of the novel features of the present invention is the fact that the pivot arm 4 is free to rotate on the pins in the supports 3 and 5. When the table 6 is in the unfolded or utility position as shown in FIG. 2, the back of the table is held level by torque on the leg or legs 7 rather than by a stop mechanism in the supports. This novel feature allows the table to always be leveled with the legs 7 on any type of terrain or surface. Since the legs 7 only fold laterally and then extend (telescope) down, it is possible for them to support considerable torque in the fore to aft direction.

Of course, a stop can be used in conjunction with the pivot supports 3 and 5 if desired as an optional feature; however, it is not necessary, and is possibly undesirable since any stop that also allows the table to be leveled requires the ability to be adjusted. With no stop, the table becomes self-adjusting to different heights.

FIG. 3 shows a different embodiment of the present invention. In this embodiment, a box 8 with an optional lid 9 is used in place of a table. This box can be used for storage, for utility, or as a sink to hold liquids. In FIG. 3, the upper pivot support 5 is shown inside the box 8. This is desirable when the structure is folded; however, it is optional whether the support 5 is inside or outside the box 8. The present invention will function just as well with the support mounted to the outside of the box 8.

The lid 9 can optionally be folded down until it is totally horizontal. In this position, it can act as a table. This feature is particularly useful when the box 8 is used as a sink or sinks for liquid. It is also possible to hinge the lid 9 on the opposite side (aft rather than forward), and have it open away from the truck. This arrangement is useful when it is desired to use the truck tailgate 2 as a seat. In this configuration, the present invention allows the user to sit on the tailgate with the box and lid adjusted to convenient height for a seated person on each side of the pivot arm 4. This use of the present invention is well suited for camping trips and tailgate parties.

Since it is immaterial whether the lid 9 hinges forward or aft, it is possible in another embodiment of the present invention to have hinges on both the front and read of the box 8. In this embodiment, the lid 9 is removable and can be attached to either set of hinges depending on whether the user wants it to open toward the truck or away from the truck. When the lid opens toward the rear of the truck, the user can sit on the tailgate if desired. The height of the table or box can be adjusted to any desired height by using the telescoping legs.

FIG. 4 shows a top view of the box 8 (the lid 9 is not shown for clarity). The box 8 in this embodiment comprises a flat utility surface 6 and one or two sinks 10. Each sink 10 can be optionally equipped with a drain 11. This allows the sinks 10 to contain liquids (for dishwashing, fish cleaning, etc.) and to be easily drained and cleaned. FIG. 4 also shows the truck tailgate 2 and the pivot arm 4. Apertures 22 that can hold cups and an optional strap 23 to hold the tailgate attach to the tailgate are shown.

FIG. 5 depicts how the present invention folds into the rear of a pickup truck when stowed for transport. FIG. 5A shows the operational or use position. The legs 7 are extended to support the box or table 8. The pivot arm 4 is extended outward from the tailgate 2.

FIG. 5B shows the present invention partially folded. The lid 9 is closed, and the pivot arm 4 is pivoted toward the tailgate 2.

FIG. 5C shows the present invention folded on the open tailgate 2. Finally FIG. 5D shows the tailgate 2 in the up position with the present invention tucked into the truck bed 12. In this position, the present invention takes up very little room in the truck bed and is ready for unfolding and use when needed.

It is also desirable to have round holes in the flat surface forming the table or lid to hold drinking cups or other liquid containers. In the embodiment containing two sinks, the upper pivot arm support can optionally be located between them on the underside of a top plate. This causes the assembly to take up less room when folded.

The present invention can be constructed entirely of metal, or other strong materials such as molded resin plastic can be used. Various combinations of materials such as metal, plastics, or composites can be used. The only material requirements are strength and durability.

To avoid excessive unwanted swivel of the table or box, it is advisable to use washers at the top and bottom pivot pins. Square plastic washers work well since they do not tend to rotate.

It is possible for the pivot pin holes to wear when softer material is used. To prevent the corner of the pivot arm from binding, that corner can be rounded.

FIG. 6 shows an embodiment of the present invention with no legs at all. The table 6 is supported by the pivot arm 4 and is locked by two brackets. One version of this legless embodiment of the present invention allows adjustment of the table 6 with an adjustment screw 13. This legless embodiment of the present invention can comprise a table or a box as previously described.

FIG. 7 shows a detail of one version of the legless embodiment of the invention. This is a fixed version with no leveling adjustment. Here the pivot arm 4 is held in place in the extended position by an upper support bracket 14 and a lower support bracket 15. The pins 16 that support the pivot arm 4 fit into elongated holes 17. When it is desired to fold the table or box for storage in the vehicle, the table or box (not shown in FIG. 7) is simply pulled upward along the axis of the pivot arm 4. The lower support bracket 15 is firmly attached to the mounting assembly, so the pivot arm 4 pulls upward and outward to where its base clears the bracket. The arm will then fold as in the other embodiments. The upper support bracket 14 is firmly attached to the table or box, so it pulls upward off the end of the pivot arm 4 clearing it so that the table or box can be folded as in the other embodiments.

FIG. 8 shows a different version of the legless embodiment of the present invention. Here, the pivot arm 4 is held by an upper support bracket 14 and a lower support bracket 15 as the version of FIG. 7; however, here, the upper support bracket 14 is attached to a hinge 18 that is itself attached to the table or box, either directly, or by supporting metal 5. Again support pins 16 fit into elongated holes 17 for folding. In this case however, an adjustment screw 19 cooperates with the upper support bracket 14 so that the table or box can be more easily leveled. The adjustment screw 19 passed through a threaded cap 20 that is firmly attached to either the table or box, or to the support metal 5. A knob 21 allows easy adjustment of the table for leveling. The tip 22 of the screw 19 moveably cooperates with the upper support bracket 14 as the screw 19 is advanced or withdrawn. The lower end of the pivot arm 4 and the lower support bracket 15 can be firmly attached to the tailgate or vehicle mounting attach or assembly 3.

It is also possible to place the adjustment screw at the lower mounting bracket instead of the upper mounting bracket, or to have two adjustment screws, one at the upper bracket and one at the lower bracket.

FIG. 9 shows a version of the legless tailgate table with the lid 9 on the box 8 opening away from the tailgate 2. In addition, an optional strap 23 is shown for attaching the tailgate attach to the tailgate.
